The Quest for New Data on the Space Star Anomaly in Pd Breakup

Abstract

Even though the development of the theories providing a precise description of few-nucleon interactions is well advanced, certain inconsistencies between experimental data and theoretical predictions are still to be resolved, one of which is the Space Star Anomaly in deuteron-proton breakup. As the cross-sections for the star configurations are measured mainly for the energy range below 20 MeV, new measurements at higher energies could give an important hint for a possible source of the discrepancy between experimental data and the theoretical predictions. In this contribution, the very first preliminary 160 MeV deuteron on proton p(d, pp)n breakup cross-sections for the star configuration measured with the BINA experimental setup are presented.
